Ubuntu 1010-1: OpenJDK vulnerabilities

Ubuntu 1010-1: OpenJDK vulnerabilities

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

Marsh Ray and Steve Dispensa discovered a flaw in the TLS and SSLv3 protocols. If an attacker could perform a man in the middle attack at the start of a TLS connection, the attacker could inject arbitrary content at the beginning of the user's session. USN-923-1 disabled SSL/TLS renegotiation by default; this update implements [More...]

Ubuntu 1011-1: Firefox vulnerability

Ubuntu 1011-1: Firefox vulnerability

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

Morten Krakvik discovered a heap-based buffer overflow in Firefox. If a user were tricked into navigating to a malicious site, an attacker could cause a denial of service or possibly execute arbitrary code as the user invoking the program. [More...]

Ubuntu 1008-2: Virtinst update

Ubuntu 1008-2: Virtinst update

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

Libvirt in Ubuntu 10.04 LTS now no longer probes qemu disks for the image format and defaults to 'raw' when the format is not specified in the XML. This change in behavior breaks virt-install --import because virtinst in Ubuntu 10.04 LTS did not allow for specifying a disk format and does not specify a format in the XML. This update adds the 'format=' option when [More...]

Ubuntu 1008-1: libvirt vulnerabilities

Ubuntu 1008-1: libvirt vulnerabilities

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

It was discovered that libvirt would probe disk backing stores without consulting the defined format for the disk. A privileged attacker in the guest could exploit this to read arbitrary files on the host. This issue only affected Ubuntu 10.04 LTS. By default, guests are confined by an AppArmor profile which provided partial protection against this flaw. [More...]

Ubuntu 998-1: Thunderbird vulnerabilities

Ubuntu 998-1: Thunderbird vulnerabilities

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

Paul Nickerson, Jesse Ruderman, Olli Pettay, Igor Bukanov, Josh Soref, Gary Kwong, Martijn Wargers, Siddharth Agarwal and Michal Zalewski discovered various flaws in the browser engine. An attacker could exploit this to crash Thunderbird or possibly run arbitrary code as the user invoking the program. (CVE-2010-3175, CVE-2010-3176) [More...]

Ubuntu 997-1: Firefox and Xulrunner vulnerabilities

Ubuntu 997-1: Firefox and Xulrunner vulnerabilities

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

Paul Nickerson, Jesse Ruderman, Olli Pettay, Igor Bukanov, Josh Soref, Gary Kwong, Martijn Wargers, Siddharth Agarwal and Michal Zalewski discovered various flaws in the browser engine. An attacker could exploit this to crash the browser or possibly run arbitrary code as the user invoking the program. (CVE-2010-3175, CVE-2010-3176) [More...]

Ubuntu 1007-1: NSS vulnerabilities

Ubuntu 1007-1: NSS vulnerabilities

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

Richard Moore discovered that NSS would sometimes incorrectly match an SSL certificate which had a Common Name that used a wildcard followed by a partial IP address. While it is very unlikely that a Certificate Authority would issue such a certificate, if an attacker were able to perform a man-in-the-middle [More...]

Ubuntu 1000-1: Linux kernel vulnerabilities

Ubuntu 1000-1: Linux kernel vulnerabilities

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

Joel Becker discovered that OCFS2 did not correctly validate on-disksymlink structures. If an attacker were able to trick a user or automatedsystem into mounting a specially crafted filesystem, it could crash thesystem or exposde kernel memory, leading to a loss of privacy. (Ubuntu6.06 LTS, 8.04 LTS, and 9.04 were not affected.) [More...]

Ubuntu 1006-1: WebKit vulnerabilities

Ubuntu 1006-1: WebKit vulnerabilities

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

A large number of security issues were discovered in the WebKit browser and JavaScript engines. If a user were tricked into viewing a malicious website, a remote attacker could exploit a variety of issues related to web browser security, including cross-site scripting attacks, denial of service attacks, and arbitrary code execution. [More...]

Ubuntu 1005-1: poppler vulnerabilities

Ubuntu 1005-1: poppler vulnerabilities

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

It was discovered that poppler contained multiple security issues when parsing malformed PDF documents. If a user or automated system were tricked into opening a crafted PDF file, an attacker could cause a denial of service or execute arbitrary code with privileges of the user invoking the program. [More...]

Ubuntu 1004-1: Django vulnerability

Ubuntu 1004-1: Django vulnerability

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

It was discovered that Django did not properly sanitize the cookie value when applying CSRF protections resulting in a cross-site scripting (XSS) vulnerability. With cross-site scripting vulnerabilities, if a user were tricked into viewing server output during a crafted server request, a remote attacker could exploit this to modify the contents, or steal [More...]

Ubuntu 1003-1: OpenSSL vulnerabilities

Ubuntu 1003-1: OpenSSL vulnerabilities

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

It was discovered that OpenSSL incorrectly handled return codes from the bn_wexpand function calls. A remote attacker could trigger this flaw in services that used SSL to cause a denial of service or possibly execute arbitrary code with application privileges. This issue only affected Ubuntu 6.06 LTS, 8.04 LTS, 9.04 and 9.10. (CVE-2009-3245) [More...]

Ubuntu 1002-1: PostgreSQL vulnerability

It was discovered that PostgreSQL did not properly enforce permissions within sessions when PL/Perl and PL/Tcl functions or operators were redefined. A remote authenticated attacker could exploit this to execute arbitrary code with permissions of a different user, possibly leading to privilege escalation. [More...]

Ubuntu 1001-1: LVM2 vulnerability

Ubuntu 1001-1: LVM2 vulnerability

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

The cluster logical volume manager daemon (clvmd) in LVM2 did not correctly validate credentials. A local user could use this flaw to manipulate logical volumes without root privileges and cause a denial of service in the cluster. [More...]
